Safety precautions
¡Before using this device, make sure to read this Instruction manual thoroughly. The cautionary items noted herein are of
the utmost importance for the safe use of this device, and should always be strictly followed.
¡Please make sure that the final user receives this Instruction manual.
¡This Instruction manual is prepared for an electrical expert.
The following symbols have been used:

DANGER

Failure to follow these instructions may result in dangerous conditions, which in
turn could lead to severe
personal injury or even
death.

CAUTION

Failure to follow these instructions may result in dangerous
conditions, which could result
in moderate to slight personal
injury or damage to equipments and facilities.

Warning for possible electrification under
certain conditions.

This means prohibition. Never ignore this
instruction.

Warning for possible outbreak of a fire
under certain conditions.

Be sure to follow these instructions without fail.

DANGER
¡Do not use this device on the conditions over ratings. Otherwise, ground-fault or short circuit fault could occur due to
dielectric breakdown. Or explosion could occur due to a short circuit protection failure.
¡Do not touch the terminals. There is a risk of electrical shock.

CAUTION
¡A qualified electrician should install this equipment.
¡Inspection and maintenance should be performed by a qualified electrician and only after shutting off the electric power
and verifying that there is no voltage present. Failure to do so could result in an electrical shock.
¡Make sure to tighten the terminal screws to the torque specified in the instruction manual. Failure to do so could result
in fire.
¡Do not install in areas subject to high temperatures, high humidity, dust, corrosive gas, vibrations, or shocks, etc. To do
so could result in malfunction or fire.
¡Install so that trash, concrete dust, iron filings or rainwater cannot get into the circuit breaker unit interior. Failure to do
so could result in malfunction or fire.
¡When the circuit breaker trips automatically, always clear the source of the malfunction before closing the circuit
breaker. Failure to do so could result in fire.
¡Terminal screws should be tightened periodically. Failure to do so could result in fire.
¡Use the breaker in 50/60 Hz. Failure to do so could result in malfunction or fire.
¡Dispose of this product as industrial waste.

Charging operation
< Manual charging >
Press the charging handle down at full stroke 7 or 8 times
until a click sounds. (It is completion when a charging handle
becomes light.) Then, the closing spring will be fully charged.
The charging indicator will show CHARGED.
The operating load is 30 N·m or less.

Charge operation: 7 to 8 times
Fig. 15-2

< Motor charging >
The closing spring is electrically charged.
This is an “ON charge method”, in which the spring is automatically charged when the breaker is closed.
¡Manual charging operation is also possible using the charging handle.
¡Pumping prevention is assured both electrically and mechanically.

¡Although the charging motor has a short time rating it can
be continuously operated for up to ten times.
¡Since the charging complete switch is separate from the
motor charging circuit, the sequence can be arranged as
required.

Opening/Closing operation
< Conditions of ON operation >
ON operation will be possible, when all the following conditions have fulfilled.
¡The breaker is OFF condition.
¡The closing spring is charged.
The charging indicator shows “CHARGED”.
¡The state without OFF operations.
•Without SHT operation
•Without mechanical lock (Padlock, Cylinder lock, Mechanical in-

Manual operation
< Closing >
Push the ON button, the breaker will close. The ON/OFF
indicator will show “ON”, and the charging indicator will show
“DISCHARGED”. Operating force is less than 50N.
(Note:)
When the OFF lock device (Padlock, cylinder lock,
castell lock etc.) is used, the closing operation should
be made after the lock is released.
Opening and closing of the drawout type breaker
must be carried out in either the CONNECT or the
TEST position.
If an under voltage trip device (UVT) is provided, its
rated voltage should be applied before attempting to
close and open the breaker.

Electrical operation

ENGLISH

Control supply

< Closing >
Remote closing can be made by emerging the closing coil (CC).
Apply the rated voltage to the control terminals A1 , A2 , and
the breaker closes.
The unit comprises an unti-pumping circuit which allows only
one action without first de-energizing then re-energizing.
To re-close the breaker, once turn off power (between A1 and
A2 ) to the closing coil, and re-apply the rated voltage to them.
When the breaker has an under-voltage trip device (UVT), the
breaker cannot be closed if power is not applied. (After power is

applied to the UVT, it takes a waiting time of 1.5 sec until the
breaker can be closed.)

Functions of electronic trip relay (ETR) parts
5 TAL LED and contact output Option
The ETR temperature detector is made functional by fitting a TAL sensor.
When the power type is P3 to P5, output is given between
513 and 564 on the control circuit terminal block. When
the temperature drops, the output will be reset. To retain

the output, take measures with an external sequence.

< Functions >
1 ERR. LED, Contact alarm output
When any abnormality or setting failure is found in ETR,
the LED alerts the operators to the abnormal status. When
the power type is P3 to P5, contact output is given between 513 and 574 on the control circuit terminal block.
•ETR function (Microprocessor, H/W)
•Mis-setting of INST. /MCR dial (P.27)
•Internal wiring of breaker related to ETR

6 MCR (Making current release) Option
Only when the breaker is turned on (from the off state), it
has the INST function. After it is turned on, the INST function will be disabled. If you specify the use of MCR when
placing an order, the MCR switch will be incorporated in
the main body. MCR will be functional by setting the INST
setting dial of ETR to the MCR side. (Refer to Fig. 20-2)

2 RUN LED (ETR)
This LED indicates that ETR is functional. When control
power is applied or approx. 10% of current flows into the
main circuit, the internal circuit will start, and the LED will
light.
3 RUN LED (Optional setting module)
This LED indicates that the optional setting module is functional.
When the control power is applied or approx. 10% of the
main circuit current flows, the LED will light.

7 Reset button
The trip indicator (LED and contact alarm output) can be

reset by pressing the “RESET” button on the front panel
of ETR or short-circuiting RS1 and RS2 on the control circuit terminal block.
(P1 and P2 types are not provided with the function to
reset the indication from the control circuit terminal block.)
A function is provided to temporarily lock LTD and STD
when the INST function is tested with the field test device.
(See the breaker tester instruction manual.)

4 Trip indicator (LED and contact alarm output)
The LED indicates the tripping or pre-alarm status. When
the power supply type is P3 to P5, contact output is given
between 513 (common) and 524 , 534 , 544 and 554 on
the control circuit terminal block.
When the current exceeds pre-alarm current setting (Ip),
the PAL LED will blink. When the LTD time (1/2 of TL) is
passed, the PAL LED will light and output the contact.

< Pre-alarm function >

The current value which is used as the reference of the load
current indication LED, varies depending on the ETR types
and characteristics setting.

When the current exceeds pre-alarm current setting (lp), the
PAL LED will blink. When the LTD time (1/2 of TL) is passed,
the PAL LED will light and output the contact.

Power supply is required for the trip indicator (LED, alarm contact output), the measurement extension module, the display
(LCD), etc. Over-current tripping, function when there is no control power supply, it operates with the energy of internal CT.
